On-board omnidirectional solid-state wind measuring device for trains

A train, solid-state technology, used in measuring devices, using differential pressure to measure fluid velocity, velocity/acceleration/shock measurement, etc., can solve the problem that the sensor cannot overcome turbulence, does not have sand resistance, high and low temperature resistance, anti-freezing, and rain resistance. The ability to resist harsh environments such as drenching can increase the effect of wind and sand resistance.

Abstract

The invention relates to a wind speed and direction measuring device, and particularly relates to an on-board omnidirectional solid-state wind measuring device for trains. The problem that an existing sensor cannot overcome the spoiler effect caused by the appearance, and is not resistant to wind and sand, high / low temperature, freezing, rain or other harsh environments is solved. According to the solid-state wind measuring device and a using method thereof developed in the invention, the differential pressure measuring method of a traditional solid-state wind measuring sensor is changed from the measuring principle, and the spoiler effect caused by the structure and shape is overcome. As the internal space is increased, necessary components for resisting the impact of harsh environments can be added, so that the wind-resistant and anti-rain performances of products are increased.

Description

technical field [0001] The invention belongs to a wind speed and wind direction measuring device, in particular to a train-mounted omnidirectional solid-state wind measuring device. Background technique [0002] The high-speed train has become the main tool of railway transportation, and its running speed is getting faster and faster. The natural wind in the environment, especially the lateral wind felt by the body during the running of the train, has seriously affected the safety of the train running. [0003] At present, similar solid-state wind sensors directly use a cylinder as the pressure sensing body, and the pressure sensing holes are opened in the orthogonal direction. The front and rear pressure pressure holes are directly connected to the positive and negative directions of the differential pressure sensor, and the orthogonal vector algorithm is used to solve the problem. The magnitude of the wind speed and direction. In order to ensure the measurement accura...
